observedY that the tool' comprises ,Primarily twolevers shaped ais shown inl the drawings Y and'Pivotallywconnected together' 'ley,lalbolt with a spring washer 9, a nut 11', andl a lockvide handles 13 and 1li; while the short arm of the corresponding levers are shaped to provide jaws 15 he observed that the upper jaw 1G is curved,l

as shown, and is provided at its end with a staple-clenching depression 17 into which the endsof'the'staple are forced when the jaws are closed, the depressionl being shaped toibend'the ends of the staple inwardly toward each other and to clench thein down flat and flush with the outer facey of the outer casing when the stapling operation is completed. rThe lower jaw 15 is substantially straight and is T-shaped at its end as indicated at 18 (Fig. 7), the top ofthe 'l--shaped portion being slightly elevated as indicated at 19 (Fig. 6) to forni in effect an anvil upon which a staple 21 is supported and by which the staple is forced into the casings. Preferably the topof this elevation 1i) is slightly concave to accommodate the'crown of the staple and prevent .its slipping laterally during the stapling operation.

A staple which is to be inserted ii ltto and through the casings is held in position'with theprongs projecting upwardly in a holder or retainer 22 shaped as shown in cross section in Fig. 7 to slidingly fit the T--shaped portion of the jaw 15 so that the holder 22 may remain stationary beneath the' inner casing when the jaw 15 moves upwardly to force the staple into the casing. A leaf spring 225 secured to the lower face of theY jaw 1o by screws 24; or other means (')veilies the inwardly projecting end 25 of'tlievstaple holder 22 and normally urges this holder 'upwardly above the jaw 15 into the position shown in Fig. 1 sothat a staple be po.

.K sitioned in the holder as shown in Figzb.

rllhe inner casing which may beV of any well known or preferred construction is indicated on the drawings. byreference character 2G, while the outer casing, from which the beads have been cut, isy indicated by ref erence character 27. After the 'outer casingV has been placed over the innercasing,as shown in these figures, one edge'of the'casing is inserted'between'the aws of ytheftool and in order to insure that` the staples will be positioned the requisite distance from the edges of the casing I have mountedupon'the jaw 15 an adj ustableabutmeht 28, which lies between the jaws 15 and 16 ahead of the pvot bolt 8, Theabutnient is fori'ned plQf-s erably integrally upon the base 29 which is equipped with an elongated slot'31 through which bolts attached to thejaw Vl5 landV equippedw'ith thumb nuts 32 project@v llt will be manifest that the abutment in ay 'be adjusted longitudinally of the jaw 15 when the lthumb nuts 32 areloosened andthat it.

and 1G respectively. llt will l may be clamped in any desired adjusted position by tightening these thumb nuts.

For the'purpose of maintaining the tool in an upright position, assliown iiiFigs. 1

vand2, during the positioning of a tire be-` tween the jaws and'during the riveting operations, lhave provided the handle 14 with diverglng legs V88 which are preferably equipped at j their vends with sharpened prongs 8l which willengage the floor or work bench upon which lthev tool'is posi'- tioned and prevent the tool from slipping about or tipping over. These prongs remain in engagement with the ioor or work bench and the tool is operatedby simply pressing down upon the handlel.

The operation of' my improved tool is substantially as follows: A staple is rst dropped into the holder, as shown in Fig'. 6, with its prongs projecting upwardly. It might be mentioned at this point that it is preferable to use staples which are so formed that the points are Vdisposed Y coaxially with thestaplo prongs so that; they will go.

straight through the tire casings without being deflected in any directionduring their insertion. One edge of the overlapped cas.

ing is then inserted between the yjaws and the abutment 28 is set, if necessary,A dependy ing upon the sizeof the tire, "to bringthe staple the requisitedistance from'the edges Y slightly beyond the outer extremity ofthe.

holder 22 and thatthe'dep'ressionorf recess 17 is arranged so as to lie" in theplaiie of the staple orthe path it will'follov/,gwhich plane isindicated vby the dotted line 2Q. In otherlwords, thedistance betweenthe .de-'j pression 17 and/the vpivot axis Yofthe jaws isfgreater than between the seat 19 and .said axis.y Should' the upper jawv L16 beccn s trufctedy so that its depression 17wwould tbey disposed,

alineinent "with the, staple channel fof the holder,` the points of Vthe staple would not enterV thesclenching depression when clenching ya staple. This will beevident from the fact that the. staple Iwill travelin a'straightV path after enteringv the inner casing, and not lin an arcuate path struckl from the. pivot axisY ofthe jaws'as la center. y The operator now presses( down upon lthe.

handleilthereby forcing the jaw 15 up wardly tov force the staple through the .eSIgS @ed into the depressioni? ,in the livvh'en the.V jaws' are y'c,ompletelyA closed,v as indicated by the Aupper jaw 16: in dotted lines, Fig. 8, in direct longitudinali removed from the holder and clenched into the casings, during which movement the upper jaw which bends them inwardly and flattens them down into the position shown in Fig. 5. The holder 22 in the meantime remains substantially stationary relatively to the casings, andas the jaw moves upwardly relatively to the holder the staple is lower end of the holder is swung outwardly, since the lower jaw travels in an arcuate path. It should be observed at this point that upon initial upward movement of the jaw 15 the holder is moved upwardly into vengagement with the inner face of the inner i casing, so that it acts as a guidefor the staple points and insures that staple will enter the casing atv the proper point and in the i proper direction, although after the staple has entered the casing it will follow a straight path as mentioned above. After the staple has been clenched the jaws are sep arated, a new staple is inserted in the holder, the casings are moved along a short distance and the operation is repeated until the cirhas been traversed,

' formed therein,

may be needed for a similarl purpose.
